DOUGH-MIXER.

Patented July 17, 1906.

Application filed May 5, 1904. Serial l-To. 206,467.

To aZZ whom it may concern:

a citizen of the United States, and a resident of Rochester, in thecounty of Monroe and State of New York, have invented certain new anduseful Improvements in Dough- Mixers, of which the following is aspecification.

This invention relates to dough-mixers," and it consists in theapparatus and combinations herein set forth and claimed.

In the drawings, Figure 1 is a top plan view of a device embodying thisinvention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1 andFig. 3 is a perspective view of a detail.

In the drawings, 1 is a pail or pan of any suitable form in which thedough is to be mixed. This pail has a handle or bail attached to theears 2 2 of the pail or pan 1, and the bail has two side parts 3 3 and aconnecting part 4. The connecting part 4 may be straight or curvedslightly upward and is adapted to engage under the corner of a table 19,as shown in dotted lines in Figs. 1 and 2, and then to hold the pail orpan 1 firmly upon the table 19.

Upon the mouth or top of the pail or pan is fastened a supportconsisting of the four arms 5 5, each having a downwardly-turned end 6,adapted to engage the top edge of the pail or pan and to fit upon thesame. The ends 6 may be of suflicient length and of such curvature as tospring over the edge of the pail or pan and to hold the support thereonby such spring action, as shown most clearly in Fig. 2. For easymanufacture the said arms are made in pairs by bending a single piece ofwire at the middle 7, Fig. 1, and placing said middle bend in a groove 8in each of a pair of corre sponding clamping-plates 9, which are heldtogether in any suitable manner, such as by the rivets 10. The grooves 88 are of such depth as to hold the wire bend 7 firmly in place when thetwo parts 9 9 are bolted or riveted together, as shown. The two clampingplates 9 have projecting hubs 11 11, and through the plates and hubspasses a stirring-rod 12. This rod passes freely through said hubsand'plates, which constitute its support, guide, and bearing, and uponits upper end is fastened a handle 13. This handle may be fastened uponthe rod in any suitable way, and said handle is adapted to bear upon theupper hub 11 and to prevent the stirring-rod 12 from descending too lowin the pail, as hereinafter explained, but permitting said rod to riseto a suitable distance in said pail, as shown in dotted lines in Fig. 2.

The stirring-rod extends downward from the clamping-plates in a straightline, then curves away from the axis, and is then curved backward uponitself in order to lie parallel and close to the bottom 14 of the pailor pan. The portion lying close to said bottom may be called thehorizontal member 15 of the stirring-rod, which is connected by thecurved portion 16 with the diagonal portion 17 to the vertical or axleportion18 of the stirring-rod.

The operation of the device is as follows: The pail or pan having beenset upon the corner of the table 19 with the bail underneath said corneris pushed away from said corner until the bail clamps the pail or panfirmly to the table.19. The sides 3 of the bail press against the edgeof the table 19, as indicated in the drawings. Flour and water are thenput into the pail or pan, either together or by putting a quantity-ofone into the pail or pan and then a quantity of the other, and thehandle 13 is turned, stirring the two materials together. The horizontalmember 15 of the stirring-rod lies close to the bottom 14 of the pail,so as to stir together all the flour and the water that may be againstit. As soon as the dough becomes thickened andstiff it will tend to liftthe stirring-rod into the position shown in dotted lines in Fig. 2, andthis action may be either automatic or be effected by the operator whenthe proper time has arrived in the mixing of the dough. When thestirring-rod has risen to said dotted-line position, on turning thehandle the dough will be worked and will be turned over and over untilit is in the proper condition. The stirring-rod moves up and down in aloose bearing in a support, consisting in the present case of theclamping-plates 9. This up-and-down motion moves the lower member 15toward and from the bottom of the pail or the supporting-surface for thedough. The lower member is made of round wire and, being substantiallystraight, has no irregulari ties of form which will tend to prevent theball of dough from turning upon it.

What I claim is 1. The combination with a pail or pan, of

the two clamping-plates having registering grooves, and thesupport1ng-w1res having bends lying in said grooves and spring endsadapted to engage over the upper edge of the pail or pan.

2. The combination with a pail or pan, of the two clamping-plates havingregistering grooves, and the supportingwires having bends lying in saidgrooves and hooked spring ends adapted to engage over the upper edge ofthe pail or pan.

3. The combination of a pail or pan, a rotary stirring-rod having asubstantially vertical member and a substantially uncurved horizontalmember adapted to rotate parallel with the bottom of the pail or pan andto constitute the axis of rotation of a mass of dough, andabearing-support for said rod car ried by said pail or pan in which therod slides vertically and automatically upward as the ball of dough onsaid horizontal member be comes thickened and stiff.

4. The combination of a pail or pan, a rotary stirring-rod having asubstantially vertical member and a substantially nncurved Witnesses:
